On a fundamental level are they, though?
I'm not talking about a replica of the Sistine Chapel or anything, but I don't think wanting a functional and at the same time attractive/well decorated base should be mutually exclusive? And that is kind of missing the point.
At the end of the day, building is building. If that's the aspect of the game I want to center around, rather than running around and looting POI'S, I would be a little angry at updates that, on the surface at least, seem to be intentionally nerfing my ability to play that way.
The "3 vowel hidding space" is definitely an issue. One I'm not sure I'd have a good answer to. That being said, I would have liked to see something that struck a middle ground. Thwarting obvious attempts to "game the game mechanics" while at the same time, not completely invalidating 70+ in-game days of building a vast bunker complex.
